mvebu: fix initramfs/kernel image for CZNIC Turris Omnia
This adds DTB to kernel and that way makes it possible to easily boot initramfs image and also kernel. The sequence to boot initramfs on Omnia is then just: env set bootargs earlyprintk console=ttyS0,115200 dhcp 0x1000000 192.168.1.1:openwrt-mvebu-cortexa9-cznic_turris-omnia-initramfs-kernel.bin bootz 0x1000000 Without this change kernel boot won't proceed and is stuck on "Starting kernel". Signed-off-by: Karel Kočí <karel.koci@nic.cz> [fixed From: to match with SoB:] Signed-off-by: Petr Štetiar <ynezz@true.cz>

I tried flashing a custom built build from today and it doesn't boot. It is stuck in "Starting kernel". I tried to reset the env with no luck.
I was able to bring it back to life with the generated medkit and 4-led recovery procedure and tried flashing the official snapshot build from today. Again same problem. I had to resort to the latest 19.07 version to be able to boot it, and avoid being killed by my entire family.
my uboot is:

Please notice that I don't know what exact commit broke my device. I suspect it was one of the many regarding booting the omnia that were made in the last month.

Feel free to revert it. I do not have Omnia available to me at the moment so i can't test it. I am going to look in to it but if you want to fix it for holidays then revert is fine with me.

Maybe FIT image will resolve this problem.
Is Turris u-boot supporting boot from FIT image?
